The National Weather service is warning drivers to beware of icy road conditions over the next 24 hours.
A winter weather advisory calling for a mix of freezing rain and sleet is in effect in southern Connecticut until 7 a.m. Tuesday, according to the NWS.
Freezing rain occurs when it rains at below-freezing temperatures, resulting in a glaze of ice that can cover all exposed surfaces.
The NWS forecast is predicting ice accumulations up to one tenth of an inch in southern Fairfield and New Haven counties.
The freezing rain-sleet mix is expected to hit southern Connecticut before 1 p.m., before switching to a rain and sleet mix for several hours.
Forecasters said there will be another window for potential freezing rain before 10 p.m. Monday night and rains overnight.
“Slow down and use caution while traveling,” the NWS said.
